To all inkom-timely concern. y

'Be it known that'I, FREDERICK J. KESTNER,

a citizen of -the'United States, residingfat Cleveland, inv thecounty ofCuyahoga and State of" Gh'iO, have invented--certain new andu's'efullfmprovements in Scaold Brackets, of" which the follow-ing islal specification.v

This invention relates to scaffold brackets,"

of that type which can be attached to the framing or-wall of abuildingfor the" purposeof supportingi'a platformy in position for Workmen.-'Ihefobjectof' the invention is to* provide an improved portable"bracket whichv can be folded' into smallVcompass, andi thereby easilytransported and setup wheredesired.

A furthergolojectA of thel invention-is to provide an improvedreversible. bracket7 which is capable of use under vvarious condi-ytions or in vario'us relations according to the brackets as willE `be`more fully apparent2 'as the description proceeds. I

l In the accompanying draWingsfF ig. l is a side elevation of thebracket attached to va Wall by nails or the like. Fig. 2 isa bottom planview of thesame. Figt 3 isasimilar view with the bracketr folded; Fig. 4is a side elevation of the bracket in reversed po' sition. Fig. 5 is aside view of the lbracket folded. Fig. 6 is a side elevation of a modi.3 tied dev-ice showing it used 1n one manner;

Fig. 7 is a similar view showing 1t used 1nv another manner; Fig. 8 is afragmentary sectional side elevation showing another' means forattaching the same to a building; Fig. .9 is a plan view of the deviceas shown in Fig. 6; Fig. 10 is a plan view of the device in foldedposition; Fig. 11 is a side elevation of Fig. l0 and Fig. l2 is a detailof the ends of the members. Y

The bracket consists of three main members or arms, indicated at 6, 7and 8. The arm or bar 6 in one position can be used as the supportingbrace, as shown in Fig. 1, and in another position cank be used tosupport the planking or platform, as shown in Fig. l1,theparts 7 and 8forming braces. Y

In the position shown in Figs. 1 and 2 the arm 6, which preferablyconsists of a straight bar of metal, is pivoted at 9 to the ears 10 of aWall plate or fixture 11, which l can be attachedy tothe outside off abuildingf Wally as' by spikes -12.v At its outer vendthis r arm'ispivotedbya pin lS13-tothe outer ends of! thefpai'rofarms7fand 8,' thepin 13 being A loose andlongI enoughy to allow the arms 7 Vand 8tospreadlaterally as well asswing vertically. Atl its outerextreniityf-the-arm 6 has afhook 1st-which iii-the other position ofvthe/bracketmaybe used `,toAhook around'a` eacharm 7 and 8 is'pivotedasindicated!jat` 16, between'the ears'17 `of wall? plateI 18whichisspiked'orfotherwise :fastened to a- Wall. Near the -r'ear' endsithearms 7 and 8' are connectedby a .pair of transverse folding linksl19.` The arms '7 andV 8 are furthermore cgnnected to the arm 6 by apairof hooked kro'd`s'20 which are hooked at 'one end as indicated at 21,in' -thefarms 7 and 8, and:y are hooked at theother end, asindicated attype of Wall or building on'whichthe bracket Q, is to belsupported.' f

A further-object ofthe invention is 'to generally improve theconstruction; of" such 22 in Sliding folded @up .01 ioop 23 whichicapable of being slid lengthwisefonfthearmV 6, to'fold; or unfoldfthemembers.L y

As stated,- the lbracket may beset 'up'withvl the arms 7? andv 8""at thetop tosupportt'he plat-form '24, the armf6 acting'asa brace. Gr, thepivotal' connectionl of? the 8-can=befreversed so that' thearmyv'can'sup'-l portthe platform, sis-indicated iny Fig. 4pFor'thispurpose the pin orbolt"l3" is re- `moved'from-the-hold+25through which=it Varms 7 andl and 5, whereby the arms 47 and 8 are swungtogether or toward each other beside the arm 6. This brings all the armsto. approximately parallel position both vertically fand laterally, and`folds the bracket into a small compass, convenient for transportation..The loose or hooked connections between the v rods 20 and the loop 22permit the rods to collapse toward each other between the bolt 13 alsopermits thearms 7 Vand to be 7 folded arms, and/the loose connection atthe spread or collapsed as described.

For use vagainst a standing Wall the bracket may be spiked to the wallas shownr in Fig. 1, or by reversing the same, the hook 14 may beengaged around a stud, as shown in Fig. 4 with the wall plates at theends of the arms 7 and 8 bearing against the-'wall to support thebracket. rlhis provides a very simple and convenient scaffold bracketfor the intended purpose.' f

The modified form shown in Figs. 6 to 12 is much the saine as that abovedescribed with the exception of the following changes. The members G and8 do not have the wall plates or xtures 11 and 18 on the ends thereof7but instead the ends aie bent as shown in the drawings at 35 and 36 andhave holes 37 therein from which extend the slots 28 so that the endscan be slipped over a nail which has been driven into the joists and canalso be removed without pulling the nails. vThe member 6 is also adaptedto be reversed for using the scaffolding in the different positions.rlhis is shown in Figs. 6 and 7 of the drawings.

When the device is'used it is necessary for the member 5 to be longer soit is provided with an extension of angle iron 29 riveted thereto andextending outwardly from the hook 14.. "On the opposite end of themember 6 is riveted a piece which will prevent the support or platforiil2l from sliding over the end thereof.

It will be noted that the bent end of the member 8 liastwo bendstherein; one at 35 and one at 31 so that it will get a bearing surfaceagainst the side of the house in whichever position it isA used eitherthat w shown in Fig. 6 or, that shown in Fig. 7;

Fig 8 shows how the device may be used in the position shown in Fig. 7without the use of nails. This is done by cutting a small hole 32 iiithe wall andft'itltiiig the device and slipping the end 35 through saidhole and letting it hook behind the wall.

as shown in Fig. 7 y

The member 6 will then rest against the outside of the wall. and the tierod 2O will-hold it. The adjustable links'19` permit theniembers 8 to benailed to studding at different distances apart, and in case there is avariation in the distance between the studs the members 19 will allowfor this variation.

I claim:

1. A folding scaffold bracket comprising a single arm provided with ahook at one end, and a pair of bracearms loosely pivoted at one end to,said single arm, to swing vertically and laterally toward the singlearm, the pivotal connection being adjustable to either end of said anglearm, a folding tie connecting the single arm and the pair of arms, andfolding links connecting the brace arms, said tie being slidable alongthe single arm.

comprising a `single arm, a pair of brace arms, means to pivotallyconnect one end ofthe bracer arms to tlie'single arm near either end ofthe latter, anda folding tie connecting the single arm and the bracearms, i I

3.11 folding reversible scaffold bracket comprising a single arm, a pairof bracel arms, means to pivotally connect one end of the braceaims tothe single arm near either endk of the latter, and a folding tieconnecting the single arm and the brace arms, andl a. pair of foldinglinks connected between the brace arms.

In testimony whereof, I afx inysignature.

in presence of two witnesses.
